MACHINERY FOR BORING- WINDOW-BLINDS.

Specification of Letters Patent No. 6,979, dated December 25, 1849.

To all whom t may concern.'

Be it known that I, JOHN VILE'Y, of New Orleans, in the parish ofOrleans and State of Louisiana, have invented a new and usefulImprovement in the -Wachine for Mortising or Boring the Frames andSlat-s of Window-Blinds, which is described as follows, reference beinghad to the annexed drawings of the same, making part of thisspecification.

Figure l, is a side elevation of the machine. Fig. 2, is a top or birdseye view of ditto. Fig. 3, is a vertical transverse section of ditto atthe line w w of Fig. 1. Fig. 4, is a section representing the eccentricsfor-raising and lowering the frame containing the auger bits. Fig. 5,represents one of the horizontal screw rods and spring attached.

Similar letters in the gures refer to corresponding parts.

The nature of this invention and improvement consists in arrangingwithin a suitable frame a horizontal frame susceptible of being raisedand lowered and containing a pair of revolvingtraversing drills in whichthe bits or other instruments for boring are inserted and arranging oneithe side of the same a sliding frame by which the frames and slats ofthe blind are moved past the bits 0r othery implements, provided withgages capable of being altered to correspond with the required distancesbetween the openings to be bored in such a manner as to bore saidopenings with accuracy without the usual measurement and with a slightexpense of power.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

A is the frame of the machine made of an oblong form of suitable size,strength, and material to contain and support the several parts.

B is an oblong skeleton metallic plate, supported in a horizontalposition above the frame of the machine by suitable legs (l) and madecurved at its ends.

C is an oblong metallic frame arranged within the plate B, consisting ofa base, having perforated rectangular blocks (2) at either end, fromwhich rise posts (3) connected together at their upper ends by a crossbar (4) and having a projection at each corner of its lower surface.

D are two horizontal drills 0r shafts inserted in the openings of therectangular blocks (2) in which they have a revolving and traversingmovement, and having grooved pulleys (a) secured to their ends next eachother and auger bits or other-tools inserted in their opposite ends.

E is an upright shaft turning in suitable boxes in the frame C betweenthe grooved pulleys (a) provided with a crank at its upper end and witha cam (b) of the form of an elipsis at near its lower end, and hava cogwheel (c) near its center immediately below the cross bar of the framec, which meshes in gear with similar cog wheels (5) o-n either side,secured on upright shafts (d) likewise turning in suitable boxes in theframe C, and provided with cams (e) similar in form to the eliptical caminthe shaft D.

F are horizontal shafts arranged lengthwise the frame, turning inopenings in ears (7) projecting from the under surface of the skeletonframe B, and having eccentrics (f) immediately under the projections atthe corners of the frame C, and bevel cog wheels g at one of their endswhich mesh in gear with similar bevel wheels secured on the extremitiesof a horizonaal transverse shaft (8) likewise turning in ears projectingfrom the skeleton plate, and provided with a ratchet wheel near itscenter with which a spring pawl (9) secured to said plate engages.

Gr are endless bands passing over the grooved pulleys (a) and over adrum secured on a horizontal transverse shaft at the lower part of themachine.

II is a sliding frame composed of two longitudinal timbers resting onprojections (l0) on the upper side timbers of the main frame, andconnected together at either end by right angle transverse bars I arerectangular blocks, secured to one of the side timbers of the slidingframe by means of T shaped tongues, inserted in corresponding grooves insaid timber, and in grooves or mortises (Z) on the inner side of saidblocks having screw shanks passing through openings in the blocks, tothe outside, on which are screwed corresponding female thumb screws(11). These blocks can be moved nearer to, or farther from each other,as occasion may require, and be clasped at any point on the timber bythe thumb screws, and conta-in slots near one end in which are arrangedright angled levers (m) turning on a fulcrum at their pins (s) on theirupper surfaces, a shortL distance beyond said grooves.

J is a graduating frame, arranged on one side of the face of themachine, consisting of a series of inclined slats or bars arrangedparallel to each other, and attached by pins at their upper ends onwhich they move to horizontal tongued sliding bars v(14) inserted inacorresponding groove (15) formed in one of the projections 10 on whichthe sliding frame H moves, the right hand one of which is clamped atpleasure by means of a clasp screw, (16) causing the whole set tolikewise remain stationary, and at their lower ends by pins in likemanner, to a grooved bar or timber (t) suspended to the frame by meansof a 3() 13111 K are hollow cast boxes containing rollers 18) turning onan upright screw shank 19) passing through said boxes and throughgrooves in the sides of the skeleton plate, and having heads (20) ontheir lower ends, and thumb screws on their upper ends, by which saidboxes are moved nearer to, or farther from the center of the machine.

L is a horizontal transverse shaft having rollers (a) secured on itsextremities, and turning in sliding boxes, moving in slots formed inuprights (c) rising from the two forward hollow boxes K, said slidingboxes being suspended by upright rods (21) passing through openings inthe upper ends of the uprights (o) and surrounded by spiral springs,between the boxes and upper ends of the slots, and provided with thumbscrews at the upperrends for raising and lowering said rollers, toconform with the thickness of the frame or slat being bored.

M are upright hollow boxes, similar to the boxes K arranged near theextremities of the skeleton plate B, through which are inserted uprightscrew shanks v(22) also passing through slots in the plate B havingthumb screws at their upper ends. These boxes have projections (23) ontheir lower parts through which pass horizontal screw rods made plain attheir outer ends, which pass through openings in projections at the endsof the plate B, having springs (a) rest-ing against projections of theplate B at their inner ends in such a manner as to allow of said hollowboxes being drawn out "secured to said cross bar on which are placedthumb screws, 25, for clamping said plates to confo-rm with thethickness of the frames.

O, are other plates secured on edge to the outer ends of the plates N,at right angles to the same having arms y, projecting inward at one end,one of which is secured to a bar, 26, inserted in grooves, 27, on thei'niier'side of said' plate and having screw shanks secured to the sainepassing through the grooves, 27, in the plate 0, and provided with thumbscrews 28.

Operation-The machine being put in motion by the application of anydesired power and the frame or stock placed between the 'hollow boxes K,M, containing the roll-` ers 18 (which are previously graduated to 90the width of the same) and secured at one end of the plates 0, byinserting the arms, y, into the end mortises of the frame stack andclamping them against the ends of the mortises by the thumb screws 28the operative moves the graduating frame J, to correspond with theacquired distance of the openings to be bored which is accomplished inthe following manner: The thumb screw 16, is unclamped and the lower endof the timber or bar (i) is either moved to the right or left on thepin, 17, as occasion may require until the abrupt ends of the inclinedslats are situated the same distance apart as the openings to be boredare intended to be-the horizontal bars or blocks 14 to which the slats,t, are attached moving in groove 15 to allow this result. He then movesthe sliding frame H, forward until thev spring stop or pawl, a, of thefirst block I, is flush against one of the ends of the slats (t) of thegraduating frame J said block I being first set at the proper point onthe longitudinal timber of the sliding frame, H to brin the points ofthe first openings to be bore immediately opposite the bits. Theoperator then turns the crank 6 until it assumes a right angle with themachine, lengthwise, which causes the center elliptical cam (b) to actupon the pulleys (a) and force the bits into the frames the properdistance to form the mortise or hole. He then brings the crank 6 to itsoriginal position, which causes the side elliptical cams (c) to act onthe pulleys (a) and withdraw the bits. He then places his thumb andforenger on the-uprights (T) (S) and by their action draws the strip orrib (p) so ascto raise the spring top or pawl (a) from contact with theend of the slat, against which it rested, and

forces the sliding frame H on its course until the stop or pawl is flushagainst the end of the next slat, when the handle 6 is moved as before,and anothermortise or hole is bored, and so on, in this manner, theoperation is repeated, until the frame is nished.

When it is desired to mortise or bore the slats and cross bars, toreceive the upright bar which connects them together and cause them tomove simultaneously in the frame, the auger bits are removed from thedrills, and other tools adapted to the purpose, substituted.

lVhat I claim as my invention and desire to secure by Letters Patent is,

l. The combination of the graduating frame J spring stops or pawls (n)bent levers (m) attached to the ribs p by chains or cords, with thesliding frame H to which the frame or slat to be bored or mortised issecured, as described.

2. I also claim the combination of the traversing arms o projecting fromthe slides moving in the plates 0 and provided with clamp screws forsecuring the ends of the frames, with the hollow traversing vboxes K, Mprovided with clamp screws, and springs, and spring rollers a, forsteadying the frame in its passage, as herein set forth.

3. I likewise claim the combination of the elliptical cams (e) securedto the upright shafts E (cl) having cog wheels 'on their upper ends,with the4 pulleys (a), in the manner, and for the purpose, herein setforth.
